Functional, precision, environmental, mechanical, EMC, etc. relays relate to Distance, Differential, O Current, U / O Voltage, U / O Frequency, motor protection, generator and ... in eyepiece laboratories. Electromagnetic compatibility EMC: Electromagnetic compatibility is the ability to operate equipment and electronic systems in electromagnetic environments, without affecting or affecting it. In fact, EMC is an important criterion for the product quality section, and in order to display the conformity of products (equipment) to the standards specified by the standard, the electronic equipment must have the relevant test approval. EMC Laboratory The EMC Lab Company has the ability to perform the following tests: EMI tests (electromagnetic interference) Radiated Emission up to 18 GHz / CISPR 22 Conducted Emission / CISPR 22 Current Harmonics / IEC 61000-3-2 Flicker / IEC 61000-3-3 EMS (electromagnetic susceptibility sensitivity) tests: ESD / IEC 61000-4-2 RF Radiated / IEC 61000-4-3 Burst / IEC 61000-4-4 Surge / IEC 61000-4-5 Power Frequency Magnetic Field / IEC 61000-4-8 Voltage Dips and Short Interruptions / IEC 61000-4-11
Advantages of EMC testing Ensure equipment is safe from sources to create transient and permanent radio frequency phenomena. EMC = EMI + EMS Electromagnetic compatibility = Electromagnetic interference + Electromagnetic susceptibility |
